Please run:

to run all update scripts for all packages that lists \`garbas\` as a maintainer
and have \`updateScript\` defined, or:
% nix-shell maintainers/scripts/update.nix --argstr package gnome3.nautilus
to run update script for specific package, or
% nix-shell maintainers/scripts/update.nix --argstr path gnome3
to run update script for all package under an attribute path.
You can also add
--argstr max-workers 8
to increase the number of jobs in parallel, or
--argstr keep-going true
to continue running when a single update fails.
